I get a brake light circuit failure that shows up on the comp randomly and then goes away. I've checked the brake light and it works. I've also checked the fuse but it is not that either. Should I just leave it be until the message stays on or until the brake lights stop working?

This happened to me a few months back, seems like it's pretty common on our cars. Replace the brake light switch located directly above the brake pedal arm (use lots of lighting and prepare to work in a tight space, on your back).
